    4. Industrial realization of bi-orientation

    Machines and industrial processes for biaxial hollow-body forming can be broadly classified into two processes:

    • the "hot" cycle, a "one-step" process. A single machine produces the bottles from the polymer granules;

    • the "cold" 2-step cycle. A first machine produces a semi-finished product, the preform, which is cooled and stored. A second machine heats and blows the preform into a bottle.

    4.1 Common operating conditions

    Molecular orientation results from stretching (in the case of monofilaments) or bi-stretching (in the case of hollow bodies or bi-stretched films) under well-defined conditions:

    • The most appropriate deformation...
